Ethermine hashrate drop

Random hashrate drops can be signs of an unstable overclock or unstable other tuning-related settings .

It is calculated based on the amount of shares you have submitted to the pool, share difficulty, and also luck . That’s why current hashrate won’t be shown as steady line, but will change – sometimes it will be higher and other times it will be lower.

If your mean hashrate is much lower then your reported hashrate, your worker is most likely overclocked too high and it’s not effectively hashing . Your hashrate may be bigger, but you’re generating more rejected or invalid hashes. Miner’s logs can confirm this in most cases.

“The Bitcoin network today has a hash rate of approximately 190 EH/s , so all the miners across the network are calculating the output of the SHA-256 cryptographic hash function approximately 190 quintillion times per second on average.”
